| Abstract |
Nowadays, for micro, small, and medium enterprises (SMEs), acquiring generic enterprise IT applications existing in the market, it is more convenient than developing a custom one. Now, the challenge is to search, select, hire, implanting (go-live) and provide continuous maintenance of the enterprise IT application that meets the needs of the enterprise. The problem is the lack of methodologies that cover this process (especially for SMEs), and those that exist are rarely available to the public. The objective of this article is to identify the process of implantation of an enterprise IT application in medium-sized enterprises. For this, an exploratory case study was carried out in an enterprise that changed the application. In this study, we interview the personnel involved in the implantation process and analyse the documentation generated. The result of this exploratory case study identifies the main motivations, difficulties and lessons learned in the implantation project. Also, an implantation process of an enterprise IT application emerged. This process consists of three phases (pre-implantation, implantation, and post-implantation) and a set of cross-cutting concerns (leadership & communication, change management, and project management). The phases have 13 stages (pre-implantation - 5, implantation - 6, and post-implantation - 2). This article ends with a discussion of it. |
